Floods, tides and tsunamis are turbulent, yet conventional models are based upon depth averaging inviscid irrotational flow equations. We propose to change the base of such modelling to the Smagorinksi large eddy closure for turbulence in order to appropriately match the underlying fluid dynamics. Our approach allows for large changes in fluid depth to cater for extreme inundations. The key to ...

This work aims to carry out a survey on municipal legislation and other legal management instruments, related the control mitigation of urban floods inundations in medium-sized municipalities state Rio de Janeiro. In this context, 22 range between 100 500 thousand inhabitants were surveyed. Among results obtained, it was found that only 13 had specific mitigate effects floods. Approximately 59%...

Sea level rise is a natural global phenomenon which is aggravated by anthropological activities. Severity of the rise varying in different parts of the world but the stress in general is increasingly threatening human development. Sustenance of a few species and their ecosystem depends on the rate and extent of rise. Coastal floods are inundations in coastal areas due to rise in sea water level...

Since 1990, we have maintained a database of historical information on landslides and floods in Italy, known as the National Research Council’s AVI (Damaged Urban Areas) archive. The database was originally designed to respond to a request of the Minister of Civil Protection, and was aimed at helping the regional assessment of landslide and flood risk in Italy. The database was compiled in 1991...

The application of numerical models to understand the behavioural pattern a flood is widely found in literature. However, selection an appropriate hydraulic model highly essential conduct reliable predictions. Predicting discharges and inundation extents are two most important outcomes simulations stakeholders. Precise topographical data channel geometries along suitable required accurately pre...

On 10th Oct. and 3rd Nov. 2018, two successive landslides occurred in the Jinsha River catchment at Baige Village, Tibet Autonomous Region, China. The blocked major river formed barrier lake, which finally caused huge flood disaster loss. hillslope landslide site has been still deforming after 2018 slidings, is likely to fail block again future. Therefore investigation of a great significance p...

In flash flood prone areas, roads are often the first assets affected by inundations which make rescue operations difficult and represent a major threat to lives: almost half of the victims are car passengers trapped by floods. In the past years, the Gard region (France) road management services have realized an extensive inventory of the known road submersions that occurred during the last 40 ...

Around the month of July 2020, people suffering from COVID-19 pandemic got added burden disastrous floods. The current study tries to understand impact flood inundation on vegetation cover across Ganga Basin with help a cloud-based computing platform like Google Earth Engine (GEE) in near real-time scenario. This offers semi-automatic scheme customized algorithms process large scale datasets fu...

Natural physical conditions and the politics of flood management provide the historical context for structural flood control that underlies modern flood hazards in the Sacramento Valley. The valley is a broad, low plain with backswamp basins that were frequently inundated prior to Anglo-American settlement, continuing until the modern flood-control system was established. Early attempts to emul...
